    Abstract: A pressure-booster output stabilizer includes: a first cylinder having therein a first chamber and a second chamber separated by a first piston; a second cylinder having therein a third chamber and a fourth chamber separated by a second piston; and a piston rod configured to couple the first piston and the second piston. The primary pressure of a pressure booster is supplied to the first chamber, the secondary pressure of the pressure booster is supplied to the fourth chamber, and the pressurized fluid is taken out from the fourth chamber.

    Abstract: A system for reducing pressure in a subsea operator. In one embodiment, a subsea system includes an operator and a deintensifier. The operator includes a housing and a piston. The piston is movably disposed within the operator housing and divides an inner volume of the operator housing into a closing chamber and a second chamber. The deintensifier is fluidically coupled to the operator. The deintensifier includes a housing and a piston. The piston includes a closing surface and an opening surface. The closing surface is fluidically coupled to the second chamber of the operator housing. The opening surface is fluidically coupled to ambient pressure. The area of the closing surface is greater than an area of the opening surface so as to increase the pressure differential between the closing chamber and the second chamber and assist in moving the operator piston to the closed position.

    Abstract: A device for riveting and a hydropneumatic device for pressure transmission, including a working piston and a transmitter piston in the form of a double-acting cylinder for transmitting pressure to the working piston, wherein a working stroke of the working piston in a working direction includes a first stroke and a subsequent second stroke, wherein the first stroke is controlled by means of pneumatic pressure acting on the working piston and the second stroke is controlled by means of pneumatic pressure acting on the transmitter piston, and wherein hydraulic fluid is displaced by the transmitter piston and the displaced hydraulic fluid effects the second stroke of the working piston. Regulation means having an actuating device are provided for regulating the pneumatic pressure on both sides of the double-acting cylinder of the transmitter piston such that the second stroke of the working piston is predefined by way of the regulation.
